Do not treat it as a FACT

Some have claimed that his article is POV-ridden, but I personally find it to go beyond that. The intro and first two chapters is not trying to convince the reader about the validity of this hypothesis, it takes it for granted, and present it more or less as a fact. To the extent of my knowledge is there no consensus regarding this hypothesis, and the article ought to reflect that. --Sparviere (talk) 23:15, 11 September 2010 (UTC)[reply]

The article begins by identifying this as a hypothesis. As I read it now there is no implication that this hypothesis is widely accepted. The Introduction should describe the hypothesis and characterize its status within the scientific community or within the history of scientific knowledge. As it stands the Introduction is already a mess due to the overeagerness of critical editors to blurt out detailed counterpoints and objections before we've even had a discussion of the hypothesis, its history, and the evidence for it, if any. This hyper-critical approach has already left us with a schizophrenic Introduction. Let's exercise some patience and let the article unfold as it would in a classroom or traditional reference book article. 75.73.91.254 (talk) 20:34, 27 December 2010 (UTC)[reply]

"The geological community generally accepts this hypothesis" Got a reference for this statement? A quick google scholar search of "snowball earth diachronous" will show several hundred counter arguments. Cwmagee (talk) 11:26, 19 October 2010 (UTC)[reply]

Late to the party, but yes, that was a ridiculous statement to have had in the article. 2603:6080:21F0:AB60:99C9:143E:34DB:FD6C (talk) 09:44, 5 August 2024 (UTC)[reply]

Timescale contradicting intro paragraph?

The intro says the hypothetical snowballs occurred earlier than 650mya, but the accompanying geological timescale graphic shows two later snowball episodes. Are these latter snowballs not included in the "Snwoball Earth hypothesis"? AxelBoldt (talk) 17:30, 26 July 2020 (UTC)[reply]

When the term "snowball Earth" was coined

The article currently lists the date of creation of the term "snowball Earth" as 1992, based on the publication of Kirschvink (1992)^[1] but this article^[2] that interviews Paul Hoffman says Kirschvink came up with it in 1989 and that seems to be a pretty reputable source. Is that sufficient to change the date listed in the article? This article^[3] also says 1989 but I'm not sure if that's more convincing since (1) it's written by the same author as the previous article and (2) the source listed in this article is snowballearth.org^[4] and thus a self-published primary source.

Evidence that refuted snowball earth

The idea of a snowball earth was defeated in a paper: Comment on ‘The Neoproterozoic (1000-540 Ma) glacial intervals: No more snowball earth?’ by Joseph G. Meert and Rob van der Voo Author links open overlay panelGeorge E.Williamsa1Phillip W.SchmidtbBrian J.J.Embletonc, where it wa shown that all the paleomagnetic data was in error and so, no snowball earth. 76.68.129.192 (talk) 22:40, 4 December 2022 (UTC)[reply]
